Uploading a pdf with new 1.5 api loses file extension / suffix

[bsdz]

When I upload a file with ".pdf" (or ".epub") extension with rmapi's put command it uploads sucessfully but drops the suffix on the server. E.g.

me@myhost:/tmp/rmapi$ ls -l
total 4488
-rw-rw-r-- 1 me me 3281197 Jul 17 20:53 sample.epub
-rw-rw-r-- 1 me me 1309513 Jul 17 20:48 sample.pdf
me@myhost:/tmp/rmapi$ rmapi put ./sample.pdf /
Refreshing tree...
WARNING!!!
  Using the new 1.5 sync, this has not been fully tested yet!!!
  Make sure you have a backup, in case there is a bug that could cause data loss!
uploading: [./sample.pdf]...OK
me@myhost:/tmp/rmapi$ rmapi ls /
Refreshing tree...

[f]	Quick sheets
[f]	sample
[f]	existing.pdf

This also means one can't upload two docs with same base name, one being epub and the other being pdf. i.e.

me@myhost:/tmp/rmapi$ rmapi put ./sample.epub /
Refreshing tree...

edit: I've realised there's a workaround which is to rename the file on the server using the "mv" command.

I think that is the default behavior by the official apps (extensions get removed)
